Are best kept with Gro-Lux lights on for 13 to 14 hours per day; with a temperature for cattleyas of 60 deg.F. at night and 70 during the day; humidity at 50 to 60 relative percent; some air circulation. A79-370

Place flasks eight to 12 inches below the Gro-Lux tubes; keep on for 18 to 20 hours daily. A70-725

The amount of Gro-Lux lighting necessary can be determined from the fact that one four-foot tube running across half-pint bottles will cover an area fifteen inches wide and four feet long; use reflection to reflect side wall light; cover with aluminium foil. A70-427

Flasks Comments
FLASKS: Best Time for Removal of Seedlings Move cattleyas and phalaenopsis to compot when seedlings are about one-inch; they are easily handled; smaller ones have been successfully transplanted, but the larger ones have a better chance of success; cover compot and give slight ventilation. A77-209 0
FLASKS: Best Time to Remove Seedlings The larger the seedlings are the better their chance for survival, providing they are not being set back in the flask. F69-149 0
FLASKS: Contamination Treatment Plant lets can be changed to a clean flask, or try Benlate alone, or Benlate at two teaspoonfuls to a gallon of water with 1/2 a teaspoonful of Truban added; use as a flush; or try Benlate alone; suggestions only, not tried. A77-209 0
FLASKS: Emptying Phalaenopsis stem cuttings removed from flask retain agar on their roots; the important thing is to remove the sugar, so soak them in water at 70 deg.F. almost one hour to remove agar and sugar before planting. A73-807 0
FLASKS: Intravenous Fluid Bottles Used in hospitals, then discarded; usually are free; the design of the rubber stoppers is ideal for sowing seed with hypodermic syringe; other advantages, refer to OD67-298 0
FLASKS: Magenta Vessels Cubical shaped, light weight plastic culture flasks or containers, easy to ship, etc.; advt. A84-1345 0
FLASKS: Of Seedlings for the Beginner Contrary to accepted wisdom, beginners can learn a lot from caring for them from the flask; something new can be learned; there's nothing to lose except ignorance. Ca82(6)-5 0
